Addendum to Los Alamos National Laboratory (SEC-00109) 

Special Exposure Cohort Evaluation Report

Purpose and Scope of this Addendum

This document provides revised excerpts from Rev. 1 of the SEC-00109 Los Alamos National 

Laboratory (LANL) SEC Evaluation Report (ER) dated August 13, 2012 (NIOSH, 2012). In that 

document, NIOSH defined a single class of employees for which NIOSH cannot estimate radiation 

doses with sufficient accuracy. The class included all employees of the Department of Energy, its 

predecessor agencies, and their contractors and subcontractors who worked at the Los Alamos 

National Laboratory (LANL) in Los Alamos, New Mexico from January 1, 1976, through December 

31, 1995.

NIOSH selected the class end date of December 31, 1995 based on its presumption that by January 1, 

1996, LANL would have been in full compliance with 10 C.F.R. pt. 835, Occupational Radiation 

Protection, which states:

§835.402 Individual monitoring.

(c) For the purpose of monitoring individual exposures to internal radiation, internal dosimetry 

programs (including routine bioassay programs) shall be conducted for:

(1) Radiological workers who, under typical conditions, are likely to receive a committed effective 

dose equivalent of 0.1 rem (0.001 sievert) or more from all occupational radionuclide intakes in a 

year.

DOE Occupational Radiation Exposure (DOE/EH-0575, 1997), Section 2.1, Radiation Protection 

Requirements, states:

10 CFR 835 became effective on January 13, 1994, and required full compliance by January 1, 

1996. In general, 10 CFR 835 codified existing radiation protection requirements in DOE Order 

5480.11. The rule provides nuclear safety requirements that, if violated, will provide a basis for 

the assessment of civil and criminal penalties under the Price-Anderson Amendments Act of 1988, 

Public Law 100-408, August 20, 1988 as implemented by 10 CFR 820 “Procedural Rules for DOE 

Nuclear Activities,” August 17, 1993.

Dose reconstruction limitations during the specified class period included the inability to bound 

unmonitored intakes of exotic alpha-emitters, fission products, and activation products. During its 

presentation of Rev. 1 of the SEC-00109 LANL ER to the Advisory Board, NIOSH indicated that it 

would continue its evaluation of these issues for the post-1995 period. 
SEC-00109 04-24-17 LANL

4 of 55 

Because this ER Addendum addresses post-1995 unmonitored intakes of the radionuclides for which 

dose reconstruction limitations were identified in Rev. 1 of the SEC-00109 ER, the evaluated class for 

this Addendum remains the same as defined in Rev. 1 except that the class start year has been changed 

from 1976 to 1996: 

Service Support Workers (which includes, but is not limited to, security guards, firefighters, 

laborers, custodians, carpenters, plumbers, electricians, pipefitters, sheet metal workers, 

ironworkers, welders, maintenance workers, truck drivers, delivery persons, rad technicians, and 

area work coordinators) who worked in any operational Technical Areas with a history of 

radioactive material use at the Los Alamos National Laboratory from January 1, 1996 through 

December 31, 2005. 

Petition Evaluation Report Addendum Summary

Class Evaluated by NIOSH (in this Addendum) 

Service Support Workers (which includes, but is not limited to, security guards, firefighters, laborers, 

custodians, carpenters, plumbers, electricians, pipefitters, sheet metal workers, ironworkers, welders, 

maintenance workers, truck drivers, delivery persons, rad technicians, and area work coordinators) 

who worked in any operational Technical Areas with a history of radioactive material use at the Los 

Alamos National Laboratory from January 1, 1996 through December 31, 2005. 

NIOSH-Proposed Class to be Added to the SEC (in this Addendum) 

NIOSH has obtained information regarding post-1995 use of exotic radioactive material at LANL as 

well as policies and procedures relating to implementation of 10 C.F.R. pt. 835. Based on its analysis 

of these available resources, NIOSH found no part of the class under evaluation for which it cannot 

estimate radiation doses with sufficient accuracy.

Feasibility of Dose Reconstruction

Per EEOICPA and 42 C.F.R. §83.13(c)(1), NIOSH has established that it has access to sufficient 

information to: (1) estimate the maximum radiation dose, for every type of cancer for which radiation 

doses are reconstructed, that could have been incurred in plausible circumstances by any member of 

the class; or (2) estimate radiation doses of members of the class more precisely than an estimate of 

maximum dose. Information available from the site profile and additional resources is sufficient to 

document or estimate the maximum internal and external potential exposure to members of the 

evaluated class under plausible circumstances during the specified period.

Health Endangerment Determination

Per EEOICPA and 42 C.F.R. §83.13(c)(3), a health endangerment determination is not required 

because NIOSH has determined that it has sufficient information to estimate dose for the members of 

the evaluated class from January 1, 1996 through December 31, 2005.

Revised Excerpts of the Evaluation Report

NOTE: FROM THIS POINT FORWARD, THIS ER ADDENDUM ONLY ADDRESSES THOSE 

SECTIONS IN REV. 1 OF THE SEC-00109 LANL ER THAT REQUIRE DISCUSSION 

REGARDING THE POST-1995 PERIOD; THEREFORE, THE SECTION NUMBERING IS NOT 

CONTIGUOUS. WHEN DEEMED HELPFUL TO THE READER, ADDITIONAL ER TEXT IS 

SOMETIMES INCLUDED FOR CONTEXT.

3.2 Class Evaluated by NIOSH

Service Support Workers (which includes, but is not limited to, security guards, firefighters, laborers, 

custodians, carpenters, plumbers, electricians, pipefitters, sheet metal workers, ironworkers, welders, 

maintenance workers, truck drivers, delivery persons, rad technicians, and area work coordinators) 

who worked in any operational Technical Areas with a history of radioactive material use at the Los 

Alamos National Laboratory from January 1, 1996 through December 31, 2005. 

3.3 NIOSH-Proposed Class to be Added to the SEC

NIOSH has obtained information regarding post-1995 use of exotic radioactive material use at LANL 

as well as policies and procedures relating to implementation of 10 C.F.R. pt. 835. Based on its 

analysis of these available resources, NIOSH found no part of the class under evaluation for which it 

cannot estimate radiation doses with sufficient accuracy.

4.0 Data Sources Reviewed by NIOSH to Evaluate the Class

As is standard practice, NIOSH completed an extensive database and Internet search for information 

regarding LANL. The database search included the DOE Legacy Management Considered Sites 

database, the DOE Office of Scientific and Technical Information (OSTI) database, the Energy 

Citations database, and the Hanford Declassified Document Retrieval System. In addition to general 

Internet searches, the NIOSH Internet search included OSTI OpenNet Advanced searches, OSTI 

Information Bridge Fielded searches, Nuclear Regulatory Commission (NRC) Agency-wide 

Documents Access and Management (ADAMS) web searches, the DOE Office of Human Radiation 

Experiments website, and the DOE-National Nuclear Security Administration-Nevada Site Officesearch. Attachment Two includes a summary of LANL documents. The summary specifically 

includes data capture details and general descriptions of the documents retrieved. 

In addition to the database and Internet searches listed above, NIOSH identified and reviewed 

numerous data sources to determine information relevant to determining the feasibility of dose 

reconstruction for the class of employees under evaluation. This included determining the availability 

of information on personal monitoring, area monitoring, industrial processes, and radiation source 

materials. 
SEC-00109 04-24-17 LANL

6 of 55 

NIOSH conducted a data capture at LANL on November 2-6, 2015. Participants included 

representatives from NIOSH, ORAUT, and SC&A. The team captured 87 documents, including 

radiation work permits, work instructions, radiological surveys, airborne sample data, and personnel 

exposure data.

In response to NIOSH data requests and questionnaires, LANL provided the following information: 

• LANL radiological policy documents 

• LANL radiological procedures documents 

• Background information on 10 C.F.R. pt. 835 implementation

• Organization charts for Health Physics (RP-1), Radiation Protection Division, and ESH Deployed 

Services Division

• List of non-routine radionuclides handled by LANL Waste Management 

• Summary of the radiation dosimetry monitoring program 

• Output from LANL’s Radioactive Sealed Sources Data Management System

NIOSH investigated the following five databases in an effort to identify “exotics” on the LANL site 

and the manner in which they were handled relative to 10 C.F.R. pt. 835 requirements: 

• LANL Nuclear Materials Management & Safeguards System (NMMSS) database: This database 

turned out to be not directly searchable; therefore, no “exotics” information was found. 

• LANL Waste Management (WM) database: This database yielded a list of non-routine 

radionuclides encountered by WM. 

• Los Alamos Historical Document Retrieval and Assessment (LAHDRA): NIOSH received DVDs 

containing images of 3,979 documents from this database, which were examined and loaded into 

the SRDB.

• DOE Nonconformance Tracking System (NTS): This database was reviewed for 10 C.F.R. pt. 835 

violations, site responses, and corrective actions. A total of 384 documents were captured, of 

which 91 were deemed potentially relevant and loaded into the SRDB. The entire list of captured 

documents is available (NTS List, 2016). The titles and SRDB Ref IDs for the 91 selected

documents are listed in Attachment 1. NTS documents considered pertinent to 10 C.F.R. 

§835.402(c)(1) and 835.702(a) compliance are discussed in Section 7.2.1. 

• DOE Occurrence Reporting System (ORPS): This database was reviewed for 10 C.F.R. pt. 835 

violations, site responses, and corrective actions. A total of 159 documents was accessed, of 

which 64 were deemed potentially relevant, captured, and loaded into the SRDB (ORPS Reports, 

1993-2015). The report topics and SRDB Ref IDs for the 64 selected documents are listed in 

Attachment 1. The result of the ORPS review is discussed in Section 7.2.1.

4.4 Previous Dose Reconstructions

NIOSH reviewed its NIOSH DCAS Claims Tracking System (referred to as NOCTS) to locate

EEOICPA-related dose reconstructions relevant to the time period under evaluation in this Addendum 

(January 1, 1996 through December 31, 2005). Table 4-1 summarizes the results of this review. 

(NOCTS data available as of December 14, 2016). 

Table 4-1: No. of LANL Claims Submitted Under the Dose Reconstruction Rule

Description Totals

Total number of claims submitted for dose reconstruction 1791

Total number of claims submitted for energy employees who worked during the period under 

evaluation (January 1, 1996 through December 31, 2005).

558

Number of dose reconstructions completed for energy employees who worked during the period 

under evaluation (i.e., the number of such claims completed by NIOSH and submitted to the 

Department of Labor for final approval).

NIOSH reviewed each claim that fell within the time period under evaluation to determine whether 

internal and/or external personal monitoring records could be obtained for the employee. As indicated 

in Table 4-1, of the total number of claims submitted for energy employees who worked within the 

time period under evaluation in this Addendum, 286 (51%) contain internal monitoring data and 458 

(82%) contain external monitoring data. 
SEC-00109 04-24-17 LANL

4.5 NIOSH Site Research Database

NIOSH also examined its Site Research Database (SRDB) to locate documents supporting the 

assessment of the evaluated class. Over 9400 documents in this database were identified as pertaining 

to LANL. These documents were evaluated for their relevance to this petition. The documents 

include historical background on external and internal dosimetry programs and evaluations, 

monitoring reports, annual environmental reports, reviews and assessments of LANL, evaluations of 

specific buildings, site surveys, and facility and process descriptions. 

4.6 Documentation and/or Affidavits Provided by Petitioners

During the evaluation conducted for this Addendum, NIOSH reviewed the following document 

submitted by the petitioner: 

• Evaluation of Continuous Air Monitor Placement in a Plutonium Facility, J. J. Whicker, J. C. 

Rodgers, C. I. Fairchild, R. C. Scripsick, R. C. Lopez; Los Alamos National Laboratory; Health 

Physics, May 1997, Volume 72, Number 5; SRDB Ref ID: Publicly available (Whicker, 1997) 

6.0 Summary of Available Monitoring Data for the Class Evaluated 

by NIOSH

6.1 Available LANL Internal Monitoring Data

6.1.1 Field Monitoring Program and Associated Data 

By January 1, 1996, the health physics field monitoring and contamination control programs at LANL 

were well-established and formalized, with over 60 procedures addressing various aspects of 

radiological protection (LANL Procedures, 1996) as well as an established process for tracking and 

notifying staff of revisions (Procedure Revisions, 1996). These procedures cover program 

administration, exposure and contamination control, monitoring, instrumentation, protective 

equipment, emergency response, and the As Low As Reasonably Achievable (ALARA) program. 

In addition to site-wide procedures, area-specific procedures and instructions were also in effect. For 

example, the stated purpose of the ESH-1/TA-55 Radiation Monitoring Instructions is “to provide 

survey frequencies which are to be used by the ESH-1 Radiological Control Technicians (RCTs) and 

Health Protection Technicians (HPTs) in assisting the NMT Division in the implementation of the 

radiological control program at TA-55” (TA-55 Instructions, 2000). This document defines the 

routine monitoring tasks of the RCTs assigned to TA-55 and delineates responsibilities. Routine 

surveys are described with survey frequencies ranging from daily to annually. These instructions also 

specify types of routine external radiation surveys as well as air monitoring and TA-55 Technical 

Safety Requirements (TSRs), which include annual CAM system calibration, monthly performance 

tests, and daily operability checks.
SEC-00109 04-24-17 LANL

NIOSH has obtained hundreds of radiological protection documents from LANL for the time period 

under evaluation. Examples include: 

• Radiological Work Permits requiring contamination surveys and air monitoring (RWPs, 1997; 

RWPs, 2003) 

• Monthly contamination surveys (Monthly Surveys, 1998; Monthly Surveys, 1999) 

• Area-specific contamination surveys (TA-3 Survey Results, 1999; TA-18 Survey Results, 1997) 

• Quarterly contamination survey summaries (Quarterly Summaries, 1999; Quarterly Summaries, 

2003) 

• Area-specific monitoring data quarterly reviews (CMR Quarterly Review, 1996; TA-55 Quarterly 

Review, 1995-1996) 

• Air sample analysis data (Air Data, 1996-1997; Air Data, 2001) 

• Air sampling/monitoring technical evaluations (Air Sampling Evaluation, 2001a; Air Sampling 

Evaluation, 2001b) 

• Airborne radioactivity investigation reports (Airborne Radioactivity, 2001; Airborne 

Radioactivity, 2002) 

• Task-specific radiological protection assessments/checklists (ESH-1 Checklist, 2001; Rad 

Protection Checklist, 1995) 

• Standard operating procedures (SOP) tracking (SOP Matrices, 1996; SOP Revisions, 1996) 

7.0 Feasibility of Dose Reconstruction for the Class Evaluated by 

NIOSH

7.2 Evaluation of Bounding Internal Radiation Doses at LANL

The principal sources of internal radiation doses for members of the class under evaluation were the 

variety of site processes and incidents involving plutonium, americium, tritium, and uranium 

(ORAUT-TKBS-0010-5). Less-common sources included Sr-90/Y-90, Th-230, Th-232, Np-237, 

Ac-227, Pa-231, Cm-244, fission products, activation products, special tritium compounds (STCs), 

and others. Although the focus of this Addendum is on these less-common sources, the 

dose-bounding methodologies described in this section may also be applicable to the principal 

radiation sources. The following subsections address the ability to bound internal doses, methods for 

bounding doses, and the feasibility of internal dose reconstruction. 
SEC-00109 04-24-17 LANL

10 of 55 

7.2.1 Evaluation of Bounding Process-Related Internal Doses

In Rev. 1 of the SEC-00109 LANL ER, NIOSH concluded that the available monitoring records, 

process descriptions, and source term data are sufficient to complete dose reconstructions for the most 

commonly-encountered radioactive materials at LANL (i.e., plutonium, uranium, tritiated water, and 

gaseous tritium) from January 1, 1976 through December 31, 2005 (NIOSH, 2012). That conclusion 

is not the primary subject of this present evaluation and remains unchanged as a result of this current 

evaluation; however, the dose-bounding methods proposed here may also be applicable to these more 

common radionuclides. 

Rev. 1 of the LANL ER also concluded that dose reconstruction for H-3 (all forms), MFP and MAP, 

Sr-90/Y-90, Th-230, Th-232, Am-241, Np-237, Ac-227, Pa-231, and Cm-244 is “likely feasible” after 

full implementation of 10 C.F.R. pt. 835 on January 1, 1996 (NIOSH, 2012). This current evaluation 

focuses on unmonitored intakes of these less-commonly-encountered radioactive materials, for which 

there are relatively few available bioassay data.

10 C.F.R. pt. 835 Regulatory Requirements 

10 C.F.R. pt. 835, Occupational Radiation Protection, specifies regulations that are pertinent to all 

DOE facilities. These regulations were issued on December 14, 1993 with an implementation 

deadline of December 31, 1995. These regulations contained specific requirements related to 

individual monitoring (§835.402) and recordkeeping (§835.702). 

The original rule, dated December 14, 1993, states the following regarding individual monitoring (10 

C.F.R. §835.402): 

§835.402 Individual monitoring. [Original rule, 1993]

(c) For the purpose of monitoring individual exposures to internal radiation, internal dose 

evaluation programs (including routine bioassay programs) shall be conducted for:

(1) Radiological workers who, under typical conditions, are likely to receive 0.1 rem (0.001 

sievert) or more committed effective dose equivalent, and/or 5 rems (0.05 sievert) or more 

committed dose equivalent to any organ or tissue, from all occupational radionuclide intakes in a 

year.

These monitoring thresholds correspond to 2% and 10%, respectively, of the occupational exposure 

limits for these categories of exposure for general employees (10 C.F.R. §835.202). The requirement 

for monitoring based on organ and tissue committed dose equivalent (CDE) was removed in 1998, as 

explained in the Federal Register notice:

The monitoring threshold based upon committed effective dose equivalent obviates the need for 

this threshold because, through application of the weighting factors defined in §835.2(b), the 

committed effective dose equivalent always provides a more restrictive basis for individual 

monitoring (63 FR 59683).
SEC-00109 04-24-17 LANL

11 of 55

The amended rule, dated November 4, 1998, states (10 C.F.R. §835.402):

§835.402 Individual monitoring. [Amended rule, 1998]

(c) For the purpose of monitoring individual exposures to internal radiation, internal dosimetry 

programs (including routine bioassay programs) shall be conducted for:

(1) Radiological workers who, under typical conditions, are likely to receive a committed effective 

dose equivalent of 0.1 rem (0.001 sievert) or more from all occupational radionuclide intakes in a 

year.

Records of conducted monitoring were required to be maintained per §835.702 in order to document 

compliance with 10 C.F.R. §835.402:

§835.702 Individual monitoring records.

(a) Records shall be maintained to document doses received by all individuals for whom 

monitoring was required pursuant to §835.402 and doses received during planned special 

exposures, accidents, and emergency conditions.

DOE Occupational Radiation Exposure (DOE/EH-0575, 1997), Section 2.1, Radiation Protection 

Requirements, states:

10 CFR 835 became effective on January 13, 1994, and required full compliance by January 1, 

1996. In general, 10 CFR 835 codified existing radiation protection requirements in DOE Order 

5480.11. The rule provides nuclear safety requirements that, if violated, will provide a basis for 

the assessment of civil and criminal penalties under the Price-Anderson Amendments Act of 1988, 

Public Law 100-408, August 20, 1988 as implemented by 10 CFR 820 “Procedural Rules for DOE 

Nuclear Activities,” August 17, 1993.

LANL 10 C.F.R. pt. 835 Implementation Documentation

10 C.F.R. pt. 835 required all DOE sites to develop a radiation protection program (RPP) document 

outlining how compliance would be achieved and certifying compliance (or indicating elements that 

were not in compliance) by the December 1995 deadline. In Rev. 1 of the LANL ER (NIOSH, 2012), 

NIOSH selected the end date of December 31, 1995 for the proposed class based on its presumption 

that by January 1, 1996, LANL would have been in full compliance with 10 C.F.R. pt. 835. 

The LANL 10 C.F.R. pt. 835 Radiation Protection Program (RPP) document, issued on May 9, 1995, 

includes the requirement for individual monitoring, as defined in 10 C.F.R. §835.402(c) (LANL RPP, 

1995, PDF p. 11). The RPP references the LANL Radiological Control Manual (LANL Rad Control, 

1994) as evidence of compliance. Article 521.1a1 of the manual states: 

The following personnel shall participate in an internal dosimetry program: Personnel who have 

the potential to receive intakes resulting in a committed effective dose equivalent of 100 mrem or 

more in a year.
SEC-00109 04-24-17 LANL

12 of 55 

In the RPP (LANL RPP, 1995), LANL acknowledges and accepts the requirements of 10 C.F.R. 

§835.402(c): 

COMPLIANCE STATEMENT: LANL accepts the requirement that for the purpose of monitoring 

individual exposures to internal radiation, internal dose evaluation programs (including routine 

bioassay programs) SHALL be conducted for radiological workers who, under typical conditions, 

are likely to receive 0.1 rem (0.001 sievert) or more committed effective dose equivalent, and/or 5 

rems (0.05 sievert) or more committed dose equivalent to any organ or tissue, from all 

occupational radionuclide intakes in a year. 

Just beneath the COMPLIANCE STATEMENT is the following: 

ACTIONS/DOCUMENTS: Verify field implementation of requirement by 6/16/95 (LANL RPP, 

1995, PDF p. 8). 

The LANL Laboratory Standard, Radiation Dosimetry Monitoring, became effective on December 23, 

1994 (LANL Dosimetry, 1994, PDF p. 15). The stated purpose of this document is to demonstrate 

compliance with dosimetry requirements set forth in 10 C.F.R. pt. 835 by establishing limits and 

implementing monitoring procedures for both internal and external exposure to radiation at the 

Laboratory. 

This Laboratory Standard begins with the following statement in its introduction:

The Laboratory personnel radiation dosimetry program is designed to demonstrate compliance 

with the radiation protection standards defined in 10 CFR 835, “Occupational Radiation 

Protection” and in the Laboratory Radiological Control Manual [LANL Rad Control, 1994].

(LANL Dosimetry, 1994).

One particularly relevant component of the LANL Laboratory Standard is the Employee Health 

Physics Checklist (LANL Dosimetry, 1994, PDF p. 34). The stated purpose of the checklist is: 

• To assess the potential radiation exposures of all personnel performing work at the 

Laboratory, including employees, affiliates, contractors, and any other non-employee workers. 

• To assign those individuals to appropriate dosimetry programs. 

The Monitoring Criteria associated with the checklist includes a requirement for routine bioassay for 

workers with a potential to receive 0.1 rem committed effective dose equivalent from all occupational 

intakes of radioactive materials in one year.

10 C.F.R. pt. 835 Compliance Assessments 

In May 1995, the LANL Internal Assessment Group conducted an assessment of the LANL Radiation 

Protection Program being implemented by LANL under 10 C.F.R. pt. 835. The team “did not identify 

any findings related to the implementation of 10 CFR 835.” In the report, entitled Assessment of the 

Radiation Protection Program at the Los Alamos National Laboratory (TITLE 10 CFR 835), October 

25, 1995 (Assessment, 1995), the only Finding was one associated with administrative controls for 

sealed sources. In addition to the single Finding, the report also included five Observations, one of 
SEC-00109 04-24-17 LANL

13 of 55 

which was relevant to internal dose assessment. Observation 4 stated that the RPP office has not 

coordinated with support organizations to implement site-specific document control and records 

management programs. Problems were identified relating to document control and distribution of 

updated procedures, including those associated with internal dose monitoring. 

The Department of Energy’s National Nuclear Security Administration conducted an independent 

review of the Internal Dosimetry Program at LANL from July 23 to July 31, 2004 (Programmatic 

Assessment, 2004). The stated Performance Requirements for the assessment included an evaluation 

of compliance with 10 C.F.R. §835.702(a). No findings or observations were made regarding 

compliance with §835.702(a), although the assessment did conclude that LANL was not in full 

compliance with the requirements in Sections 104, 701(a), 702(g), and 704(e) of 10 C.F.R. pt. 835, 

Occupational Radiation Protection. In addition, the Laboratory was not in compliance with the 

requirements in Sections 122(d)(1) and 122(e)(1) of 10 C.F.R. pt. 830, Nuclear Safety Management. 

The three non-compliance Findings noted in the assessment report were: 

• Finding 1: LANL plutonium internal dosimetry documents are not current with respect to revision 

date, requirements, and incorporation of ICRP-60 models. 

• Finding 2: Internal dosimetry document hierarchy is not clearly defined or consistent with HSR-12 

Quality Assurance Program Plan (QAPP) nor does it meet regulatory procedure requirements. 

• Finding 3: LANL's Internal Dosimetry Program scope is not clear. 

These Findings, along with the Observations identified in the report, are primarily associated with 

procedural documentation of the internal dosimetry program. No issues were identified in the 

assessment that questioned the validity of the internal dose calculations. The review team also noted 

that “LANL’s Internal Dosimetry Program is staffed with experts, resulting in calculations of internal 

dose estimates that are technically sound.”

10 C.F.R. pt. 835 Exemption for Radon 

Although radon is not considered a major source of radiation exposure for LANL workers, for 

completeness, it should be noted that LANL requested and appeared to receive DOE approval for an 

exemption from certain 10 C.F.R. pt. 835 requirements related to Rn-220 and Rn-222 (Radon 

Exemption, 1995). Specifically, LANL requested that guidance contained in ICRP-65 be used to 

establish DAC values for Rn-220 and Rn-222 (ICRP Pub. 65, 1993). As a result, the DAC values for 

each of these nuclides was increased by a factor of 2.5.

Nonconformance Tracking System (NTS) Findings 

NIOSH reviewed the DOE Nonconformance Tracking System for LANL 10 C.F.R. pt. 835 violations, 

site responses, and corrective actions. A total of 384 documents were captured (NTS List, 2016), of 

which 91 were deemed potentially relevant and loaded into the SRDB (see Attachment 1).
SEC-00109 04-24-17 LANL

14 of 55 

The following two findings are considered pertinent to compliance with 10 C.F.R. §835.702(a): 

• NTS-ALO-LA-LANL-LANL-1999-0014. NC ID: 652 (SRDB 164538). Noncompliance to the 

LANL Radiation Protection Program. Finding #3 of this report states: 

Records: (a) Non-laboratory exposure data was not included in all employee records for current 

year or lifetime dose. In some cases, when an employee’s previous employer provided dose 

information, it was not included in the employees’ current year or lifetime dose. 

• NTS-ALO-LA-LANL-LANL-2003-0002. NC ID: 1377 (SRDB 164618). Noncompliance to the 

LANL Radiation Protection Program. Finding #4 of this report states: 

The Cumulative Total Effective Dose Equivalent (CTEDE) received by each individual as 

recorded and reported by LANL does not include doses received at other locations as required by 

the amended (1998) 10 CFR 835 rule. While such information is requested and ordinarily 

received, it is not routinely incorporated into the dose history database and reported. This 

noncompliance has been previously identified in NTS-ALO-LA-LANL-LANL-2000-011 and is 

currently being addressed through corrective actions contained therein. 

The above two findings would not likely affect NIOSH’s ability to perform individual dose 

reconstructions. This is because NIOSH considers all relevant dosimetry data from all sites for a 

claimant when performing dose reconstructions, regardless of whether such data were properly 

combined previously by a given site. 

NIOSH did not identify any findings in these reports relating to non-compliance with 10 C.F.R. 

§835.402(c)(1). 

Occurrence Reporting System (ORPS) Findings 

NIOSH reviewed the DOE Occurrence Reporting System for LANL 10 C.F.R. pt. 835 violations, site 

responses, and corrective actions. A total of 159 documents was accessed, of which 64 were deemed 

potentially relevant, captured, and loaded into the SRDB (ORPS Reports, 1993-2015) (see Attachment 

1 for a list of report topics). Following its review of these selected documents, NIOSH concluded that 

none of the findings was pertinent to 10 C.F.R. pt. 835 compliance. 

7.2.3 Methods for Bounding Internal Dose at LANL

7.2.3.3 Bounding Methods by Radionuclide 

Based on its review of radioactive material use at LANL and the associated radiation protection 

programs, NIOSH has concluded that intakes for unmonitored workers with access to controlled areas 

were unlikely to have resulted in committed effective dose equivalents (CEDE) in excess of 0.1 rem 

per year. This conclusion is based upon the implementation of 10 C.F.R. §835.402, which required 

personnel monitoring for workers who are likely to receive a CEDE of 0.1 rem or more from all 

occupational radionuclide intakes in a year. 10 C.F.R. §835.702 required that all associated personnel 

monitoring data be recorded and maintained. Therefore, in the absence of internal dosimetry records, 

NIOSH may assume that intakes by unmonitored workers did not result in doses exceeding 0.1 mrem 

CEDE.
SEC-00109 04-24-17 LANL

15 of 55 

Bounding intake quantities corresponding to a CEDE of 0.1 rem may be defined as 2% of the 

stochastic Annual Limit on Intake (ALI), or SALI. The ALI is defined in 10 C.F.R. §835.2 

(Definitions). The SALI is the value of intake of a given radionuclide in a year by the reference man 

(ICRP Pub. 23, 1975) that would result in a CEDE of 5 rem (0.05 sievert). The DAC quantities 

published in 10 C.F.R. pt. 835, applicable to the period under evaluation in this Addendum, are based 

on U.S. Environmental Protection Agency’s Federal Guidance Report No. 11, Limiting Values of 

Radionuclide Intake and Air Concentration and Dose Conversion Factors for Inhalation, Submersion, 

and Ingestion, published September 1988 (EPA FGR-11, 1988). Since inhalation is the predominant 

pathway for worker intakes, the CDE conversion factors presented in Table 2.1, Inhalation, of U.S. 

EPA FGR-11 was used to determine the SALI for each radionuclide of interest, using the value 

presented in the “Effective” column.

Table 7-1 shows the bounding annual intake quantities for selected LANL radionuclides for 

unmonitored workers with access to controlled areas.

An unmonitored worker with access to controlled areas may be assumed to have been exposed to 2% 

of the SALI per year from any of these potential radionuclides. For purposes of bounding dose 

reconstruction, the radionuclide and lung clearance class selected for each year’s intake would be the 

one resulting in the highest dose to the organ of interest at the time of cancer diagnosis. 

The methodologies described in ORAUT-OTIB-0054, Fission and Activation Product Assignment for 

Internal Dose-Related Gross Beta and Gross Gamma Analyses, may be used to bound potential 

intakes to MFP and MAP. The specific 2%-SALI nuclide mixture (fission products and activation 

products) resulting in the highest dose to the organ of interest at the time of cancer diagnosis would be 

the selected intake.

Intakes of radon and their progeny by unmonitored workers with the potential for exposure may be 

bound by assuming an exposure of 40 DAC-hr per year. During the period under evaluation, 

10 C.F.R. pt. 835 permitted the DAC values for Rn-220 and Rn-222 to be replaced by 1 working level 

(WL) and 1/3 WL, respectively. DCAS-TIB-011 provides a method for converting exposures 

expressed in working level months (WLM) into individual organ doses. A WLM is equivalent to 170 

WL-hours. Therefore, 40 DAC-hrs is equivalent to 0.24 WLM for Rn-220 and 0.078 WLM for 

Rn-222. 

Special Tritium Compounds (STCs) 

Potential dosimetric issues associated with special tritium compounds (STCs), including stable metal 

tritides (SMTs) and organically bound tritium (OBT), were not formally recognized or addressed by 

LANL or DOE until the late 1990s. The 1998 LANL report, Los Alamos National Laboratory 

Radiological Dose Assessment - Tritium Internal Dosimetry and Bioassay Programs does specifically 

address bioassay for STCs (Inkret, 1998a). 

Although the LANL internal dosimetry program was modified in the late 1990s to accommodate 

STCs, the potential for significant exposure to these compounds was small and dose assessments were 

rarely deemed necessary. Consequently, bioassay data specific to STCs are rare for the entire period 

of this evaluation. This situation is similar to that of the exotic alpha-emitters, where dose assessment 

capabilities existed, but internal dosimetry data are few due to their rare usage.

NIOSH can, however, bound unmonitored intakes of STCs in the same manner as intakes from other 

rare nuclides for which it lacks internal dosimetry data. This can be done by assuming that intakes of 

these compounds by unmonitored workers with access to controlled areas were unlikely to have 

exceeded 2% of the SALI. The SALI for STCs, applicable to the time period of this evaluation 

(January 1, 1996 through December 31, 2005), would be equivalent to that derived from the rule for 

tritiated water vapor. (DAC values specific for STCs were first promulgated in the 2007 revision of 

10 C.F.R. pt. 835.) Dose reconstruction for intakes of STCs may be performed using the 

methodologies outlined in ORAUT-OTIB-0066.

7.2.4 Internal Dose Reconstruction Feasibility Conclusion 

In Rev. 1 of the SEC-00109 LANL ER, NIOSH defined a single class of employees for which NIOSH 

cannot estimate radiation doses with sufficient accuracy (NIOSH, 2012). The class included all 

employees of the Department of Energy, its predecessor agencies, and their contractors and 

subcontractors who worked at the Los Alamos National Laboratory in Los Alamos, New Mexico from 

January 1, 1976 through December 31, 1995. 

Dose reconstruction limitations during this period included the inability to bound unmonitored intakes 

of exotic alpha-emitters, fission products, and activation products. Because extensive bioassay 

programs were in place for plutonium and uranium, no dose reconstruction infeasibilities were 

identified for these materials. The tritium bioassay program was also extensive; however, NIOSH 

committed to continue to evaluate dose reconstruction feasibility for organically bound tritium (OBT) 

and stable metal tritide (SMT) tritium forms. 

In that previous evaluation, NIOSH selected the class end date of December 31, 1995 based on its 

presumption that by January 1, 1996, LANL would have been in full compliance with 10 C.F.R. pt. 

835, Occupational Radiation Protection. 10 C.F.R. §835.402 required personnel monitoring for 

workers who were likely to receive a CEDE of 0.1 rem or more from all occupational radionuclide 

intakes in a year. 10 C.F.R. §835.702 required that all associated personnel monitoring data be 

recorded and maintained. Therefore, in the absence of internal dosimetry records, NIOSH may 

assume that intakes by unmonitored workers did not result in doses exceeding 0.1 mrem CEDE. 

The final rule for 10 C.F.R. pt. 835, Occupational Radiation Protection, was published on December 

14, 1993 with an effective date of January 13, 1994. All DOE sites were required to be in compliance 

with the rule by January 1, 1996. 

This Addendum addresses post-1995 unmonitored intakes of the radionuclides for which dose 

reconstruction limitations were identified in Rev. 1 of the SEC-00109 ER, and assesses the feasibility 

of dose reconstruction for such unmonitored workers. During the course of this evaluation, 

documentation relating to implementation of 10 C.F.R. pt. 835 was reviewed, particularly those 

documents associated with 10 C.F.R. §835.402, along with LANL and DOE compliance assessments 

and NTS and ORPS reports. These reviews did not reveal any compelling evidence to contradict 

NIOSH’s previous presumption that, by January 1, 1996, LANL would have been in compliance with 

10 C.F.R. §835.402. Given the presumption of compliance, the absence of internal dosimetry records 

indicates that unmonitored workers were deemed unlikely to have received intakes resulting in a 

CEDE 0.1 rem or more from all occupational radionuclide intakes in a year. 

In conclusion, for the period of this evaluation (January 1, 1996 through December 31, 2005), NIOSH 

finds that it has access to sufficient information to: (1) estimate the maximum radiation dose for every 

type of cancer for which radiation doses are reconstructed, and that could have been incurred in 

plausible circumstances by any member of the class; or (2) estimate radiation doses of members of the 

class more precisely than an estimate of maximum dose.

7.5 Other Potential SEC Petition Issues Identified During the Evaluation

The issue of neptunium hazards, monitoring, controls, and dose estimation has been raised at the 

LANL site. In a supporting document provided by the petitioner, neptunium is discussed as part of a 

2005 DOE inspection. In this section, NIOSH follows this issue as it makes its way through the DOE 

noncompliance system and evaluates whether the quantities and processes involving neptunium and 

the issues surrounding the LANL radiological safety program affect NIOSH’s ability to bound dose 

for potential Np exposures.

Information Provided by the Petitioner

Included in the supporting documents received from the petitioner on May 23, 2008, is a November 

2005 report by the DOE Office of Security and Safety Performance and Assurance entitled, Inspection 

of Environment, Safety, and Health Programs at the Los Alamos National Laboratory. This report 

includes the following discussion regarding neptunium (LANL Inspection, 2005):

Radiological hazards are prevalent throughout TA-55. However, these hazards also have not 

always been subjected to appropriate evaluation through work planning mechanisms and 

interface between line management and HSR [Health, Safety and Radiation Protection Division]. 

For example, in NMT-11, radiological hazards are identified but the unique hazards associated 

with use of neptunium during fuel production are not adequately called out, analyzed, or 

documented. Standard plutonium controls, such as plutonium bioassays, would not be adequate 

for neptunium but were not evaluated and/or modified for this operation. The process hazards 

analysis, HCPs [Hazard Control Plans], and work instructions for actinide fuels work do not 

adequately define or analyze the special hazards posed by the use of 100-gram quantities of 

neptunium powders by NMT-11 workers; for example, the site’s standard bioassay program and 

TA-55 health physics questionnaire are only designed to account for plutonium, uranium, 

americium, and tritium. Specific controls must be put in place to ensure that appropriate 

neptunium bioassays are performed following workplace events involving neptunium because the 

standard plutonium bioassay would be ineffective in detecting or quantifying neptunium intakes. 

Further, the HSR-12 protocol for placing individuals on a routine bioassay program indicates that 

NMT-11 fuel production workers handling 100 gram quantities of neptunium may need to be on a 

routine neptunium bioassay program. Calculations performed by HSR-12 following Independent 

Oversight’s inquiry indicated a threshold of nearly 1700 grams; however, the calculations were 

based on a release fraction of 0.001 for “solids and spotty contamination” versus a release 

fraction of 0.1 for “nonvolatile powders,” which is more reflective of what NMT-11 handles. 

Using the latter release fraction, a threshold quantity of as low as 10 to 20 grams may warrant 

routine bioassay for neptunium in accordance with ANSI/HPS N13.29-2001, which the site uses to 

determine routine bioassay needs.

In addition to bioassay concerns, there are also potential inadequacies in the assessment of 

neptunium airborne contamination from instruments designed and calibrated for plutonium. The 

lack of comprehensive hazards analysis has resulted in the lack of an appropriate, documented 

technical basis for addressing these issues.
SEC-00109 04-24-17 LANL

19 of 55 

Finding #8. Potential radiological hazards posed by neptunium and isotopes other than 

plutonium, americium, uranium, and tritium are not adequately addressed by existing LANL TA55 hazards analysis processes or HSR mechanisms. 

Summary. A variety of methods are used to identify hazards associated with activity-level 

program work. Process hazards analyses and HCPs identify hazards inherent in one or more 

groupings of similar manufacturing or research activities. At the task level, these documents are 

supplemented by work instructions and IWDs [Integrated Work Documents], which more 

specifically document the unique hazards a worker may encounter during operations. IMP-300.2 

and its predecessor Notice 142 require linkage of hazards (and controls) to individual work steps, 

thereby enhancing the previous LANL work control processes. In most cases, the hazards analysis 

mechanisms result in a comprehensive listing of hazards associated with work activities. However, 

lack of required SME [Subject Matter Expert] involvement limits the effectiveness and accuracy of 

hazards analysis efforts. Insufficient rigor and analysis of hazards posed by chemicals and use of 

non-routine radioactive material at TA-55 has resulted in potentially inadequate controls. 

DOE Preliminary Notice of Violation, EA-2006-05 

On February 16, 2007, DOE issued a Preliminary Notice of Violation (PNOV), EA-2006-05, to the 

University of California, Los Alamos National Laboratory. This notice was issued, in part, in 

response to the November 2005 inspection report cited above. This notice includes the following 

discussion (PNOV, 2007, PDF pp. 24-25): 

III. Radiological Protection Violations

...C. Monitoring 

10 CFR 835.401, General Requirements, requires that “(a) Monitoring of individuals and areas 

shall be performed to (2) Document radiological conditions; and (6) Identify and control potential 

sources of individual exposure to radiation and/or radioactive material.” 

10 CFR 835.403, Air Monitoring, requires that “(a) Monitoring of airborne radioactivity shall be 

performed, (2) As necessary to characterize the airborne radioactivity hazard where respiratory 

protection devices for protection against airborne radionuclides have been prescribed. (b) Realtime air monitoring shall be performed as necessary to detect and provide warning of airborne 

radioactivity concentrations that warrant immediate action to terminate inhalation of airborne 

radioactive material.” 

Contrary to the above, on multiple occasions LANL failed to adequately perform and/or document 

radiological monitoring intended to identify radiological conditions, identify potential sources of 

exposure, or characterize airborne respiratory hazards. Specific examples include: 

6. The Office of Independent Oversight 2005 inspection found that LANL failed to adequately 

establish personnel and area monitoring for TA-55 hazards of neptunium and isotopes other 

than uranium, plutonium, americium and tritium. Specific examples include: 
SEC-00109 04-24-17 LANL

20 of 55 

a. In NMT-11, radiological hazards are identified but the unique hazards associated with use 

of neptunium during fuel production are not adequately called out, analyzed or 

documented. 

b. The process hazards analysis, hazard control plans, and work instructions for actinide 

fuels work do not adequately define or analyze the special hazards posed by the use of 

100-gram quantities of neptunium powders by NMT-11 workers. 

c. The site’s standard bioassay program and TA-55 health physics questionnaire are only 

designed to account for plutonium, uranium, americium and tritium. 

d. A documented technical basis has not been established to demonstrate that instruments 

designed and calibrated for plutonium will function adequately in detecting neptunium 

airborne contamination. 

In its conclusion, the PNOV states that, pursuant to the provisions of 10 C.F.R. §820.24(b), the 

University of California is required to submit a written reply within 30 days. This reply is to include: 

(1) admission or denial of the alleged violations; (2) any facts set forth which are not correct; and (3) 

the reasons for the violations if admitted, or if denied, the basis for the denial. In the event the 

violations are admitted, this PNOV will constitute a Final Order (PNOV, 2007, PDF pp. 28). 

LANL Reply to DOE Preliminary Notice of Violation, EA-2006-05 

On March 5, 2007, LANL replied to PNOV EA-2006-05 (PNOV Reply, 2007). The reply was very 

brief and acknowledged that the violations occurred as stated in the PNOV and waived LANL’s right 

to contest the Notice. The reply mentions DOE meetings with University of California representatives 

in August 2006 to discuss the following: 

• April 2005 LANL investigation into the TA-50-66 worker uptakes 

• July 2005 National Nuclear Security Administration (NNSA) Type B investigation of the offsite 

americium contamination event

• November 2005 Environment, Safety and Health Inspection performed by SSA's Office of 

Independent Oversight

• March 2006 LANL Summary of Recent Reports for Institutional Price-Anderson Nuclear Safety 

Noncompliances 

At the latter meeting, there was a discussion of the causal factors detailed in the 2006 LANL 

Integrated Corrective Action Project (ICAP) (ICAP, 2006). On June 1, 2006, site management 

transferred from University of California to LANS, LLC. UC/LANL completed 21 of the identified 

compensatory actions and corrective actions by May 31, 2006. Twelve more actions had been started 

and were transferred over to LANS, LLC on June 1, 2006. LANS, LLC reviewed the remaining 58 

actions and submitted an updated ICAP to the Los Alamos Site Office on September 11, 2006. 

There is no mention of neptunium in the LANL reply to the PNOV. However, violations are entered 

into the DOE Noncompliance Tracking System (NTS) for follow-up action (see below). 
SEC-00109 04-24-17 LANL

21 of 55 

DOE NTS Reports Related to LANL for 2005 and 2006 

Violations cited in DOE PNOVs are entered into the DOE Noncompliance Tracking System (NTS) 

for follow-up action. Based on the discussion in the LANL reply to PNOV EA-2006-05 (cited 

above), NIOSH reviewed the following LANL-related NTS reports for 2005 and 2006 for Np-related 

discussions: 

• NC ID: 1877, Unexpected Building, Personnel and Off-Site Contamination Discovered

• NC ID: 2106, Dose to Workers from Radioactive Material Inhalation in TA-50-66

• NC ID: 2305, Integrated Corrective Action Project

• NC ID: 2306, Airborne Release of Radioactive Contamination in the TA-55 Vault

Although the above reports discuss a variety of radiological program issues from the 2006 PNOV, 

neptunium is not specifically mentioned. 

LANL Responses to NIOSH Inquiry Regarding Neptunium

In a data request to LANL dated December 4, 2012 (NIOSH Data Request, 2012), NIOSH asked the 

following: 

A specific Np-237 issue has been a recurring subject in Advisory Board Work Group meetings and 

remains unresolved. The petitioner cited a specific situation in which the monitoring employed 

may have been inappropriate. This concerned an October/November 2005 inspection of LANL 

Environment, Safety & Health programs conducted by the DOE Office of Independent Oversight’s 

Office of Environment, Safety and Health Evaluations. Page 35 of their report describes a 

situation in which standard plutonium controls, including plutonium bioassay, were 

inappropriately used for an operation involving Np-237. Can you provide any details on this 

situation?

On March 19, 2013, LANL provided the following responses (LANL Response, 2013): 

In the case of Np-237, the need for monitoring was formally evaluated in 2006. The quantity of 

Np-237 being used fell far below the monitoring criteria calculated by reference to established 

plutonium monitoring criteria and the dose potential of neptunium relative to plutonium. The 

quantities of Np-237 that would trigger internal monitoring were subsequently incorporated into 

the LANL Internal Dosimetry Technical Basis document [LANL Technical Basis, 2010].
SEC-00109 04-24-17 LANL

22 of 55 

The [November 2005 DOE inspection] report contained the following Finding (Finding #8): 

Potential radiological hazards posed by neptunium and isotopes other than plutonium, americium, 

uranium, and tritium are not adequately addressed by existing LANL TA-55 hazards analysis 

processes or HSR mechanisms.

To address the issue specifically for neptunium work, internal dosimetry SMEs confirmed the 

appropriate threshold for requiring internal dose monitoring at 1700 g. This was documented in 

Radiological Dose Assessment Technical Issue Paper 018 (TIP 018) in 2006 [TIP 018, 2006]. The 

conclusion was that workers associated with this finding were not required to be on additional 

internal dosimetry programs driven by their work with neptunium. 

NIOSH Considerations Regarding LANL Neptunium Monitoring

NIOSH reviewed information regarding the handling and monitoring of neptunium at LANL. NIOSH 

considered the following points:

• NIOSH has identified a difference in the radiological program documentation before and after 

2005-2006. The 1993 document, Internal Dosimetry and Dose Assessment at Los Alamos 

National Laboratory, has a technical basis for internal dosimetry that mentions monitoring for 100 

mrem; however it does not specifically mention Np (Inkret, 1993). The 2010 LANL document, 

Internal Dosimetry Technical Basis, mentions Np and the threshold quantity that would require 

internal dose monitoring (1.7 kg or more of Np-237) (LANL Technical Basis, 2010).

• In a 1998 paper on dose assessment at LANL, there is information regarding routine bioassay 

monitoring for workers likely to receive 100 mrem CEDE, but no specific mention of Np (Inkret, 

1998b, PDF p. 9). 

• A 2004 assessment of the LANL Internal Dosimetry Program does not specifically mention Np, 

but it does provide feedback that the site does not account sufficiently for all radionuclides in 

internal dosimetry. The assessment also states that LANL does not have TBDs for all required 

radionuclides (Programmatic Assessment, 2004, PDF p. 10). 

• NIOSH has not located specifics regarding quantities of Np used, only that use was rare. The 

controls employed appear to be those in place for plutonium-related work. In the 2005 DOE 

inspection report, NMT-11 workers are discussed using “100 gram” quantities (LANL Inspection, 

2005).

• PNOV EA-2006-05 discusses several incidents/violations in Section III (PNOV, 2007). It also 

discusses a general issue identified by the Office of Independent Oversight in 2005 in regard to the 

hazards of Np in T-55; however, no Np-specific violations or examples are identified. 

• The 2005 and 2006 NTS reports related to PNOV EA-2006-05 (i.e., NC IDs: 1877; 2106; 2305; 

2306) discuss Radiological Program issues but never mention Np (ICAP, 2006; NC ID: 1877, 

2005; NC ID: 2106, 2005; NC ID: 2306, 2006).

• The 2010 LANL document, Internal Dosimetry Technical Basis, states: “Individuals who work 

with 1.7 kg or more of Np-237, and individuals with previous confirmed intakes of neptunium, are 
SEC-00109 04-24-17 LANL

23 of 55 

monitored annually by RAS [alpha spectroscopy]” (LANL Technical Basis, 2010). LANL has 

maintained that no worker ever reached this threshold value to be monitored. 

NIOSH Conclusions 

The 2005 inspection conducted by the DOE Office of Independent Oversight, indicated that LANL 

failed to adequately establish personnel and area monitoring for hazards associated with neptunium. 

The examples presented in this report described inadequate hazards assessments, insufficient 

documentation of hazards, inadequate work planning, issues associated with the site’s bioassay 

program procedures, and air monitoring technical basis documentation. While these issues appear to 

be legitimate concerns, they do not indicate that unmonitored intakes occurred. 

Work involving neptunium was rare at LANL during the period of this evaluation, January 1, 1996 

through December 31, 2005. The specific example discussed in the 2005 inspection report and 2007 

PNOV involved the use of “100-gram quantities” of neptunium. There appears to have been some 

disagreement between the DOE inspection team and the LANL subject matter experts regarding the 

need for routine bioassay for workers using 100-gram quantities of neptunium. The DOE inspection 

team referenced ANSI/HPS N13.29-2001 and concluded that the bioassay threshold could be as low as 

10 to 20 grams of neptunium powder. The threshold determined by LANL was 1700 grams. LANL’s 

contention therefore, was that routine bioassay monitoring thresholds were never exceeded. 

NIOSH has not found any evidence of any breech in containment during these operations that resulted 

in significant release of airborne neptunium contamination. Given the robust field monitoring program 

described in Section 6.1.1, it is highly unlikely that such a release of material could have occurred 

without eventual detection. NIOSH has not found any evidence suggesting that unmonitored workers 

received neptunium intakes as a result of these operations. The 2005 DOE inspection report did not 

suggest or imply that unmonitored workers received neptunium intakes. 

In conclusion, NIOSH finds that unmonitored workers involved with these operations were unlikely to 

have received intakes that would have resulted in 100 mrem CEDE. Therefore, the methodology 

described in Section 7 for bounding intakes for unmonitored workers is also appropriate for workers 

involved with these neptunium operations.

7.6 Summary of Feasibility Findings for Petition SEC-00109

This Addendum evaluates the feasibility for completing dose reconstructions for employees at LANL 

from January 1, 1996 through December 31, 2005. NIOSH found that the available monitoring 

records, process descriptions, and source term data available are sufficient to complete dose 

reconstructions for the evaluated class of employees.

Table 7-2 summarizes the results of the feasibility findings at LANL for each exposure source during 

the time period January 1, 1996 through December 31, 2005.

8.0 Evaluation of Health Endangerment for Petition SEC-00109

The health endangerment determination for the class of employees covered by this evaluation report is 

governed by both EEOICPA and 42 C.F.R. §83.13(c) (3). Under these requirements, if it is not 

feasible to estimate with sufficient accuracy radiation doses for members of the class, NIOSH must 

also determine that there is a reasonable likelihood that such radiation doses may have endangered the 

health of members of the class. Section 83.13 requires NIOSH to assume that any duration of 

unprotected exposure may have endangered the health of members of a class when it has been 

established that the class may have been exposed to radiation during a discrete incident likely to have 

involved levels of exposure similarly high to those occurring during nuclear criticality incidents. If 

the occurrence of such an exceptionally high-level exposure has not been established, then NIOSH is 

required to specify that health was endangered for those employees who were employed for a number 

of work days aggregating at least 250 work days within the parameters established for the class or in 

combination with work days within the parameters established for one or more other classes of 

employees in the SEC. 

This present evaluation is specific to internal dose reconstruction feasibility at LANL for the period 

from January 1, 1996 through December 31, 2005. In Rev. 1 of the SEC-00109 Petition Evaluation 

Report (August 13, 2012), NIOSH concluded that it was feasible to reconstruct internal dose from 

plutonium and uranium for this period, but concluded that it was only “likely” feasible to reconstruct 

internal dose to all radionuclides, including exotics. As a result of this present evaluation, NIOSH 

now concludes that it has access to sufficient information to estimate the maximum radiation dose for 

every type of cancer for which radiation doses are reconstructed, and that could have been incurred in 

plausible circumstances by any member of the class for the period from January 1, 1996 through 

December 31, 2005. 

NIOSH’s evaluation determined that it is feasible to estimate radiation dose for members of the 

NIOSH-evaluated class with sufficient accuracy based on the sum of information available from 

available resources. Therefore, a health endangerment determination is not required. 

9.0 Class Conclusion for Petition SEC-00109

Based on its full research of the class under evaluation, NIOSH found no part of said class for which it 

cannot estimate radiation doses with sufficient accuracy. This class includes all on-site personnel who 

worked at the Los Alamos National Laboratory site from January 1, 1996 through December 31, 

2005. 

NIOSH has carefully reviewed all material sent in by the petitioner, including the specific assertions 

stated in the petition. NIOSH has also reviewed available technical resources and many other 

references, including the SRDB, for information relevant to SEC-00109. In addition, NIOSH 

reviewed its NOCTS dose reconstruction database to identify EEOICPA-related dose reconstructions 

that might provide information relevant to the petition evaluation. 

These actions are based on existing, approved NIOSH processes used in dose reconstruction for 

claims under EEOICPA. NIOSH’s guiding principle in conducting these dose reconstructions is to 

ensure that the assumptions used are fair, consistent, and well-grounded in the best available science. 
SEC-00109 04-24-17 LANL

26 of 55 

Simultaneously, uncertainties in the science and data must be handled to the advantage, rather than to 

the detriment, of the petitioners. When adequate personal dose monitoring information is not 

available, or is very limited, NIOSH may use the highest reasonably possible radiation dose, based on 

reliable science, documented experience, and relevant data to determine the feasibility of 

reconstructing the dose of an SEC petition class. NIOSH contends that it has complied with these 

standards of performance in determining the feasibility or infeasibility of reconstructing radiation dose 

for the class under evaluation.

Attachment 1: DOE Database Results (NTS and ORPS)

The attachment lists the documents obtained as a result of searching the contents of two DOE 

databases: (1) the Nonconformance Tracking System (NTS); and (2) Occurrence Reporting System 

(ORPS). The purpose of the searches was to discover any evidence of 10 C.F.R. pt. 835 violations at 

LANL, the site’s response, and the corrective actions undertaken. 

Documents Obtained from the DOE’s Nonconformance Tracking System (NTS)

NIOSH reviewed the DOE Nonconformance Tracking System (NTS) for 10 C.F.R. pt. 835 violations,
